A) GPS monitoring of plate speeds and movements.
Explanation:
The most recent evidence supporting the theory of plate tectonics would be GPS monitoring of plate speeds and movements.
A GPS is a Global Positioning System made up of series of components.
- Plate tectonics theory is the movement of the earth's lithosphere relative to one another.
- The recent advances uses a GPS system to monitor real-time movement of the plates.
- The GPS system is made up of a system of satellite in space that communicates real-times locations to sensors on the earth surface.
- From the sensors, observatory stations can know and duly observe how plates are moving.

Answer:
All the elements of a period have similar chemical properties because they have the same number of valence electrons in their outermost shell. Their atoms have the same number of electrons in the highest occupied energy level
The one that will change the velocity of a periodic wave is :
B. Changing the medium of the wave
Waves is always determined by the properties of the medium, which means that changing the medium will change the velocity of the wave

Answer:
They are known as isotopes
Quoting from the article itself:
"Since it is above Earth's atmosphere, it gives us clearer pictures of space than telescopes on Earth can."
